Evo VIII backfiring
So I have an 05 Evo and recently it has aqcuired a backfire under load in the middle of a gear. It mostly happens in third but has happened in first and fourth. It does not happen all the time but still does every once in awhile. Has anyone had this problem before or know what it may be?

check them, only 6k miles after I replaced mine with Denso's the gap had some how gotten to big so i had to re gap them....then a while later same thing...so i ended up throwing them out for NGK's a few hundred miles ago.

ya but ive had the full exhaust for awhile now and the backfiring just started one day. It backfired after shifts when i first put it on but never in the middle of a gear under load.
